Collectively, three American national scenic trails, over 2,000 miles each, that more or less run north to south: the Appalachian Trail, the Pacific Crest Trail (PCT), and the Continental Divide Trail (CDT). A “Triple Crowner” is an individual who has hiked or is currently hiking all three of the Triple Crown trails, in any order, and not necessarily as thru-hikes.
Example: “I think it’s incredible that Buffalo is finishing his Triple Crown when he’s only 21!”
Fun Facts: In 1972, Eric Ryback became the first Triple Crowner after thru-hiking the AT at age 16, the PCT at age 17, and the CDT at age 19. In 2013, Reed Gjonnes became the youngest triple-crowner at age 13. In 2005, Matthew Hazley became the first person to walk the Triple Crown continuously, in 239 days.
